Overview
Thank you for purchasing the R100 Wireless Gateway. The R100
complies with IEEE 802.11g and 802.11b standards. The 802.11g is
an extension to 802.11b (used in the majority of wireless LANs today)
that broadens 802.11b’s data rates to 54 Mbps within the 2.4 GHz
band using OFDM (orthogonal frequency division multiplexing)
technology. The 802.11g allows backward compatibility with 802.11b
devices but only at 11 Mbps or lower, depending on the range and
presence of obstructions. Wireless LANs are complementary
extensions to existing wired LANs, offering complete mobility while
maintaining continuous network connectivity to both corporate and
home Intranets. They add a new level of convenience for LAN users,
as PC’s stay connected to the network anywhere throughout a building
without being bound by wires. This is accomplished through the use
of the Access Point functionality of the Wireless Gateway. The builtin Internet gateway capability allows your family to share a broadband
Modem and one ISP account simultaneously from different rooms
without wires!

Configuring the R100 Wireless Gateway
The gateway can be configured to meet various usage scenarios. Some
of the factory default settings may suit your usage, however, others
may need changing. Prior to using the gateway, you must check the
basic settings to guarantee it will work in your environment. Configuring
the gateway is done through a web browser. You need a Notebook PC
or desktop PC connected to the gateway (either directly or through a
network hub) and be running a web browser as a configuration terminal.
The connection can be wired or wireless. For the wireless connection,
you need an IEEE 802.11g/b compatible device (e.g. a WLAN Card,
installed in your Notebook PC). You should also disable WEP and set
the SSID to “default” for your wireless LAN device. If you want to
configure the gateway or want to access the Internet through the
gateway, the TCP/IP settings must be correct. Normally, the TCP/IP
settings should be on the IP subnet of the R100 Wireless Gateway.
3. Utilities
Note: Before rebooting your computer, the R100 Wireless Gateway
should be switched ON and in the ready state.
Setting an IP address for the Wired or Wireless Connection
Getting the IP Automatically
The R100 Wireless Gateway
incorporates a DHCP server so
the easiest method is to set your

To set up your wireless interface,
you must first give it an SSID
(Service Set Identifier). The SSID
is a unique identifier attached to
packets sent over WLANs. This
identifier emulates a password

SSID
The SSID is an identification string of up to 32 ASCII characters that
differentiate one R100 Wireless Gateway Access Point (AP) from
another. The SSID is also referred to as the “ESSID” or “Extended
Service Set ID.” You can use the default SSID and radio channel unless
more than one R100 or Access Point is deployed in the same area. In
that case, you should use a different SSID and radio channel for each
R100 or Access Point. All R100 Wireless Gateways and Diamond
Digital 802.11g/802.11b WLAN client adaptors must have the same
SSID to allow a wireless mobile client to roam between the R100s. By
default, the SSID is set to “default”.

Chapter 3 - Software Configuration
Channel
The 802.11g and 802.11b specifications supports up to 14 overlapping
channels for radio communication. To minimize interference, configure
each 802.11g AP to be non-overlapping; select Auto from the Channel
drop-down list to enable the system to select a clear channel during
boot up as your operating channel.
Ensure that any R100 Wireless Gateways sharing the same channel
(or channels which are close in number) are as far away from each
other as possible, based on the results of your site survey of the
facility. There is a site survey utility on the R100 Driver CD.
Wireless Mode
This field allows you to specify the transmission rate. Selecting Auto
(recommended) allows 802.11g and 802.11b clients to connect to the
R100 Wireless Gateway. Selecting 54G Only maximizes performance,
but prevents 802.11b clients from connecting to the gateway. If 54g
Protection is checked, G-Mode protection of 11g traffic is enabled
automatically in the presence of 11b traffic. Select 802.11b only when
backward compatibility is needed for some older wireless LAN cards
with a maximum bit rate of 2Mbps.
3. Utilities
Authentication Method
This field enables you to set different authentication methods which
determine different encryption schemes. The relationship between
Authentication Method, Encryption, Passphrase and WEP Keys is
listed in the following table. If you are not using a RADIUS server in a
home environment and all your clients support WPA, using WPA-
PSK is recommended for better security. If WPA or Radius with 802.1x,
is selected, additional settings for the RADIUS server in the Wireless
– Radius field are required.
Encryption (WEP)
Traditional WEP encryption is applied when Open or Shared Key,
